To all whom t may concern: l

Be it known that we, EUGENE RILEY ED- soN and BENJAMIN F. SILLIMAN, citizens of the United States of America, residing at Cleveland, in the county ot' Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Driers; andwe do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in driers, and pertains more especially to a drier comprising a sectional jacketed interiorlychambered horizontally-arranged cylinder which forms the drying-chamber of the drier and is closed at its ends by suitably-applied One object of this invention is to render the drier long-lived by the formation of the drying-chamber by several separable and circumferentially-adjustable cast-iron annular cylinder-sections assembled endwise betweenthe heads of the drier and forming'the surrounding wall of the said chamber, with the said wall hollow or interiorly and circumferentially chambered to form a heating-jacket.

Another object is to form in the construction of each annularcylinder-section an annular cast-iron outer or jacket-forming shell, which is formed integral with the inner annular cast-iron shell which the said cylindersection comprises, with each cylinder-section provided at each end and externally with a laterally and outwardly projecting annular flange, with adjacent angesof adjacent cylindersections separably secured together, with the outer shell of each cylinder-section Aenough larger diametrically than the inner shell of the said cylinder-section to form between the said shells an annular heatinguid-receiving chamber extending circumferentially of the said cylinder-section, and with communication between the annular heatingfiuidreceiving chambers ofadjacent cylinder-sections suitably established.

Another object of this invention is to render the construction simple and convenient in the assemblage and renewal of parts.

lWith these objects in view and to the end of realizing other advantages hereinafter appearing this invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a side elevation, largely in central section, of a drier embodying the invention which constitutes the subject-m atter of this application. Fig. 2 is a transverse vertical section on line 2 2, Fig. l, looking in the direction indicated by the arrow. Fig. 3 is a section on the curved line 3 3, Fig. 2, looking in the direction indicated by the arrow. j

Our improved drier comprises an interiorlychambered jacketed cylinder composed of annular sections a, assembled endwise and horizontally arranged in line between two heads b, which close opposite ends, respectively, of the drying-chamber formed by and interiorly of the said cylinder. The cylinder ofthe drier illustrated is therefore arranged horizontally and comprises live annular sections a. Each cylinder-section @comprises an inner cylindrical cast -iron shell c, surrounded bya jacket-forming outer cylindrical cast-iron shellf. The outer shellfof each cylindrical section a is enough longer diametrically than the inner shell c of the said section to form between the said shells an annular heating-fluid-receiving chamber n, which extends circumferentially of the said cylinder-section. Each cylinder-section ct is provided at each end and externally with a laterally and outwardly projecting annular ange d. Each cylinder-section is provided interiorly of its chamber fn, and centrally between the ends of the said section with radially-'arranged webs c, which tie together andbrace apart the shells c and fof the said section and strengthen the latter.

The chamber n of each cylinder-section C! has end walls g, which extend circumferentially of the said section, which walls g are slotted or perforated laterally, as at r, to form ports arranged at suitable intervals circumferentially of the said cylinder-section. Communication between the chambers n of adjacent cylinder-sections a is established by the ports r of the adjacent end walls g of the said sections, and the said ports are arranged, preferably, next to the inner sides of the outer shellsfof the said cylinder-sections.

The cent-ral and two end cylinder-sections a correspond in dimensions and construction in every respect, and the two remaining and intermediate cylinder-sections c correspond in dimensions and construction in every respect. All the cylinder-sections correspond in construction so far as the assemblage of the parts is concerned, and the said sections are therefore interchangeable.

Adjacent sections a are separably secured together by suitably-applied bolts and nuts. Adjacent flanges d of adjacent cylinder-sections a have registering horizontally-arranged holes s, extending laterally therethrough at suitable intervals circumferentially of the said cylinder-sections and engaged by bolts t, and correspondingly threaded nuts u are mounted upon the screw-threaded shanks of the said bolts, and the arrangement of the parts is such that the said cylinder-sections a have their said flanges clamped together by and between each bolt t and the nut u upon the said bolt. It will be observed, therefore, that adjacent cylinder-sections a are separably clamped together.

Each intermediate cylinder-section a, interposed between the central section o, and an end section a, is provided with two pipe connections w and WV, arranged diametrically opposite and at the top and bottom, respectively, of the drier, which pipe connectionsneXtend through the chamber n of the said intermediate section and have their interior passage-ways communicating with the main or drying chamber of the drier. A

By the construction hereinbefore described it will be observed that upon loosening the nuts u, instrumental in clamping adjacent cylinder-sections a together, each of the said sections is rendered free to be turned independently of the other of said sections, and hence the cylinder-sections are adjustable circumferentially.

In the drier, as illustrated in Fig. l, the pipe connections W form the material-discharging outlets of the drying-chamber of the drier, through which outlets material is removed from within the said chamber, whereas the pipe connections w form charging apertures and vapor-outlets, through which the said chamber is supplied with material to be dried or heated within the said cham ber and which accommodate the escape of vapors and gases from the said chamber.

The heads b, which close the ends of the Y'Mdr-"4'ng-chamber of the drier, are preferably with stuffing-boxes G, which surround the suitably-supported stirring-shaft K, which is arranged horizontally and extends centrally through the drier. The shaft K is provided within the drying-chamber with radially-arranged stirring-arlns- L. Preferably each head b is provided at its outer side with a bracket which affords bearing to the shaft K. The shaft K is provided at one end with a driving-wheel t to which power is applied in any approved manner. Each head b is provided with two diametrically opposite ports H and D, arranged near the top and bottom, respectively, of the said head and communicating with ports o', formed in the adjacent end wall g of the chamber n' of the adjacent end cylinder-section ct. It will be observed also that the ports H form the steaminlets of the jacket of the drier, whereas the ports D constitute the drain passage-ways of the said jacket.

The upper portions of the shells c of the cylinder-sections a, because of their greater exposure to iron-corroding vapors and gases arising from material treated within the drying-chamber, become worn more rapidly than the lower portions of the said shells, and consequently the importance of the circumferential adjustability of the cylinder-sections a is obvious. When, therefore, the upper portions of the shells c of the cylinder-'sections a become worn to such an extent that a readjustment of the said sections is deemed advisable, the nuts u are loosened to accommodate the said readj ustment, whereupon the cylinder-sections a are turned half-way round, and then the pipe connections W will be the charging-aperto res or vapor-outlets of the drier, the pipe connections w will form material-discharge passage-ways, the ports l-I will be drain passage-ways, and the ports D will form steam-inlets. Of course the nuts u are retightened upon a readjustment of the cylinder sections a. By the construction hereinbefore described it is obvious also that any two cylinder-sections showingr a great difference in the wear of their shells c may be interchanged to advantage.

The slots or ports fr in each of the adjacent end walls g of adjacent cylinder-sections ct register with the slots or ports r in the other of the said walls. The arrangement of the said ports r of each end wall g of each chamber n circumferentially of the drier is such that the chambers n of the end cylinder-sections a are in either adjustment of the said sections and heads h in communication with the ports H and D of the said heads and communication between the chambers n of adja cent cylinder-sections is in either adjustment of the said sections established at and centrally of the bottom of the said chambers, so that any water resulting from condensation of steam within the said chambers can freely pass between the said chambers.

The arrangement of the bolt-holes s of ad- IOO IIO

jacent flanges dof adjacent cylinder-sections a is such that the holes s in each of the said flanges shall register with the holes s in the other of the said flanges in either adjustment of the said cylinder-sections.

' Each head I) is shown provided in Fig. 1 with two pipes P and Q, which communicate with the ports H and D, respectively, of-the said head and are each provided with a normally closed valve R. In the position of the heads illustrated the pipes P are employed to conduct steam through the ports H and the connected ports r in the end cylinder-sections into the heating-uid-receiving chambers a of the said cylinder-sections, and the pipes Q are employed as drain-pipes to drain from the said chambers n through the ports y D and the connected ports?n of the said cylinder-sections any water accumulating within the saidchambersn; but obvionsly'when the said heads b are circnmferentially adjusted or turned half-way round the pipes Q will then be used as steam-pipes and the pipes P will then be used as drain-pipes.

The drier illustrated is shown resting upon two standards J, arranged below opposite ends, respectively, of the drier, and the drier is removably secured` to the said standards by some of the same bolts and nuts employed in securing the heads b to the end cylindersections.
